INTRODUCTION Nematodes of Trichostrongylus genus are mainly parasites of herbivores, although sporadic human infections have been reported in many countries. OBJECTIVE To describe the frequency and seasonality of Trichostrongylus spp. infection in individuals attended at a public clinical laboratory. MATERIALS AND METHODS Fecal samples of 9,283 individuals were evaluated by spontaneous sedi...

the effect of a new anthelmintic compound, leavo-tetramisole, in the mass-treatment of several intestinal helminthes has been evaluated during a study undertaken among the population of the village of zavieh hajian, located about 10 km northwest of dezful, khuzestan.in the autumn of 1972, a total of 83 inhabitants, 65 of whom were simultaneously infected with ascaris, hookworm (ancylostoma) and...

BACKGROUND Infection with Trichostrongylus spp. is common among human and herbivorous in most parts of Iran, especially in southern and northern areas. The aim of present study was to identify Trichostrongylus spp. among human population using excreted egg specimens, by the molecular method, in Mazandaran Province, northern Iran. METHODS Overall, 33 positive fecal specimens were randomly samp...

Trichostrongylus eggs observed in cellophane-thick smears are difficult, in practice, to distinguish from hookworm eggs. In order to overcome these limitations, a molecular approach was conducted. A Trichostrongylus colubriformis adult worm was obtained from a human in Laos, which was identified morphologically. ITS-1 sequence of this worm was determined, and found to be most similar with that ...

As the prevalence and severity of anthelmintic resistance continue to rise, nematode infections in sheep correspondingly reduce the profitability of the sheep industry. In Costa Rica, sheep production systems are increasing in both number and importance. A field trial study was carried out to detect the level of anthelmintic resistance to albendazole and ivermectin in gastrointestinal nematodes...

ABSTRAK Kiraan telur cadng dalam najis dan kehadiran spesis-spesis nematod pada kambing daripada tujuh kandang kambing yang kedl di daerah Timur Laut, Pulau Pinang telah dikaji. Secara amnya kiraan telur adalah tinggi, berjulat antara 500 2000 epg. Keadaan iklim didaerah ini adalah sesuai bagi kehidupan dan perkembangan sekurang-kurangnya lima spesis nematod iaitu Cooperia spp., Haemonchus spp....

BACKGROUND Haemonchus contortus and Trichostrongylus spp. are reported to be the most prevalent and highly pathogenic parasites in livestock, particularly in small ruminants. However, the routine conventional tool used in Malaysia could not differentiate the species accurately and therefore limiting the understanding of the co-infections between these two genera among livestock in Malaysia. Thi...

From July 1979-December 1980, 48 springbok were culled for a parasite survey at Benfontein. Lice were the dominant parasites and reached a peak in September. Damalinia antidorcus, Linognathus antidorcitis, Linognathus armatus and Linognathus euchore were the most prevalent species, nymphs in most cases outnumbering adults. During the winter months, 2nd and 3rd instar Rhinoestrus antidorcitis an...

background: infection with trichostrongylus spp. is common among human and herbivorous in most parts of iran, especially in southern and northern ar-eas. the aim of present study was to identify trichostrongylus spp. among hu-man population using excreted egg specimens, by the molecular method, in mazandaran province, northern iran. methods: overall, 33 positive fecal specimens were randomly sa...

This study aims to investigate the occurrence of gastrointestinal parasites in goats from the Western Santa Catarina, Brazil. Twenty four farms were analyzed in 17 different municipalities. Animals (n=217) from different production purposes (milk and meat) and age were randomly chosen. Fecal samples were collected from the rectum stored in plastic bottles and transported to the laboratory in po...
